Throwing my hands up on this ignition!
Does anyone know the actual difference between PRIMARY CURRENT AND SECONDARY CURRENT? READ about the LAWS OF ELECTRICAL properties !
SNIPPED to shorten quote.....
I have an AS in electrical engineering and was a licensed electrician for 43 years and use to have to buy the NEC books. So I know about primary and secondary coil operation.
If you did not post 1 paragraph of 50+ lines most folk's may stop and read what you posted but 90% will just scan your running on post and not know.
If you cool your jets and read what I posted above about the gauge wire feeding the coil, it is about AMP's to the COIL PRIMARY. If you limit Amps to the primary you will get reduced Secondary voltage output.
True there are very little amperage at the secondary side, Milli-amps in fact.
You must use low voltage and high Amps to transform it to High Voltage but low Amps, and the other way around.
High tension power lines running overhead on those 300 foot steel towers is in the 1,000,000's of volts. It is stage 1 of primary that feeds sub stations. The sub stations use transformers to take those millions of volts and makes stage two primary in multi phase 17.5Kv, 7.2Kv..... Whatever is needed down the line.
And then in stage three, the transformer outside your house/shop takes that 17.5K VAC and makes the the 1 phase 240 V or 208, 480 3 phase. With the drop from Million VAC to Kv's and then to your secondary needs, the transformer provides more AMP's.
Again, you must use low voltage and high Amps to transform it to High Voltage but low Amps, and the other way around.
In telephone Central Offices they use 48 volts DC for everything inside except lights and test gear. The lines on the street uses that 48 Volts @ 600 Miliamps up to 30,000 feet at times so you have dial tone at the house/shop. When they go over 30,000 feet, somewhere near the center they add what is called a 'Load Pot' that has lots of load coils in it. When they put these load coils in, they up the line voltage to 54 Volts DC and the load coil boosts the output amperage up some. You may have 54 VDC incoming and 48-52 VDC outgoing....
